Getting the Stack Trace in a Release Flash Player

Developers have been asking for the ability to get the stack trace of errors in the release Flash Player. With the release of Flash Player 11.5 Beta this feature makes it debut. This is a beta release but I wanted to show you what it looks like and explain what this feature is about.

Flash Player Release Player – before 11.5 beta

Flash Player Release Player – with 11.5 beta (swf-version=18)

You’ll notice that the new feature is missing the file classpath and line details that are present in the debug player stack trace. This makes sense because the debug symbols are not included in the release SWF. Even so, just having the class and method information of the stack trace will help a lot when tracking down those weird bugs. You know the ones that only show up with real users in the wild using your app with release versions of Flash Player.
